Modified Files:
	src/sys/arch/xen/conf [bouyer-xen2]: files.xen
Added Files:
	src/sys/arch/xen/x86 [bouyer-xen2]: bus_dma.c

Log Message:
bus_dma(9) for xen. Derived from arch/x86/x86/bus_dma.c.
bounce buffers not supported yet, because xen doesn't have an interface
to request memory in a specific range (this means that DMA on ISA won't
be supported), but I've left the code commented out because xen will
likely provide an appropriate hypercall in the future.
